Request-Response pattern

[Deleted user]

Sometimes an actor should send a response on a received message. To this we should implement:

1. The ID message pattern
2. The Correlation ID message pattern
3. A timeout event handler if an actor doesn't receive a response in a bounded time.

In additional using request-response pattern should be transparency for any actor. In other words an actor should not know wheither it sends response or it resends received message to other actor.
